每日英語跟讀 Ep.K374: Scientists Find No Benefit to Time-Restricted Eating

The weight-loss idea is appealing: Limit your eating to a period of six to eight hours each day, during which you can have whatever you want.

減肥的方法很有吸引力:將你的飲食限制在每天六到八小時,在此期間你可以吃任何你想要的東西。

Studies in mice seemed to support so-called time-restricted eating, a form of the popular intermittent fasting diet. Small studies of people with obesity suggested it might help shed pounds.

對老鼠的研究似乎支持所謂的限時飲食,這是一種流行的間歇性禁食飲食。對肥胖人群的小型研究表明,它可能有助於減輕體重。

But now, a one-year study in which people followed a low-calorie diet between the hours of 8 a.m. and 4 p.m. or consumed the same number of calories anytime during the day has failed to find an effect.

但現在,一項為期一年的研究表明,人們在上午 8 點到下午 4 點之間遵循低熱量飲食。或在一天中的任何時間消耗相同數量的卡路里都沒有發現效果。

The bottom line, said Dr. Ethan Weiss, a diet researcher at the University of California, San Francisco: “There is no benefit to eating in a narrow window.”

最重要的是,舊金山加利福尼亞大學的飲食研究員 Ethan Weiss 博士說:“在狹窄的時間裡吃飯沒有任何好處。”

The study, published in the New England Journal of Medicine, was led by researchers at Southern Medical University in Guangzhou, China, and included 139 people with obesity. Women ate 1,200 to

1,500 calories a day, and men consumed 1,500 to 1,800 calories daily. To ensure compliance, participants were required to photograph every bit of food they ate and to keep food diaries.

該研究發表在《新英格蘭醫學雜誌》上,由中國廣州南方醫科大學的研究人員領導,包括 139 名肥胖患者。女性吃了 1,200 到每天 1,500 卡路里,男性每天消耗 1,500 到 1,800 卡路里。為確保合規,參與者被要求拍攝他們吃的每一口食物並記錄食物日記。

Both groups lost weight — an average of about 14 to 18 pounds — but there was no significant difference in the amounts of weight lost with either diet strategy. There also were no significant

differences between the groups in measures of waist circumference, body fat and lean body mass.

兩組都減輕了體重——平均約 14 至 18 磅——但兩種飲食策略的體重減輕量沒有顯著差異。也沒有顯著各組在腰圍、體脂和瘦體重方面的差異。

The scientists also found no differences in such risk factors as blood glucose levels, sensitivity to insulin, blood lipids or blood pressure.

科學家們還發現血糖水平、對胰島素的敏感性、血脂或血壓等風險因素沒有差異。

“These results indicate that caloric intake restriction explained most of the beneficial effects seen with the time-restricted eating regimen,” Weiss and his colleagues concluded.

“這些結果表明,熱量攝取限制解釋了限時飲食方案的大部分有益效果,”Weiss 和他的同事總結道。

Christopher Gardner, director of nutrition studies at the Stanford Prevention Research Center, said he wouldn’t be surprised if time-restricted eating nonetheless worked on occasion.

斯坦福預防研究中心營養研究主任克里斯托弗·加德納(Christopher Gardner)表示,如果限時飲食偶爾奏效,他也不會感到驚訝。

“Almost every type of diet out there works for some people,” he said. “But the take-home supported by this new research is that when subjected to a properly designed and conducted study — scientific investigation — it is not any more helpful than simply reducing daily calorie intake for weight loss and health factors.”

“幾乎所有類型的飲食都適用於某些人,”他說。 “但這項新研究支持的結論是,當進行適當設計和進行的研究——科學研究——它並沒有比簡單地減少每日卡路里攝入量來減輕體重和健康因素更有幫助。”Source article: https://udn.com/news/story/6904/6294472
